  1. Thanks for the instructions. I have done this however it only works on a new e-mail. Is there a setting somewhere so that the signature works on replies and fwd e-mails as well?

    1. Hi Matt,

      When you put in your signature, it should also work for replies and forwards. When replying or forwarding an email, you may need to expand the window in order to see your email signature there. If you don’t expand the window, it doesn’t show you the signature.

      Hope that makes sense.

  2. My jpeg or picture will not show up on my signature in the iOS outlook app. I have copied and paste from my outlook on my pc, but the image will not show. Please advise.

    1. Hi Michael,

      Unfortunately, the Outlook app for both iOS and Android doesn’t support HTML signatures. This means you can only have a plain text email signature (with no images) when you use it.

  3. After creating my signature I sent a test and my signature block is double spaced not single spaced. Us there a way to correct this?

    1. Hi Dot,

      If you’ve installed your signature in Outlook App for iOS, it will convert the signature from HTML to Plain Text. This is because the Outlook App doesn’t support HTML signatures. Sometimes, in the process of converting it from HTML to Plain Text, it will add double spaces in between the signature fields.

      Feel free to send through a few screenshots to us so we can take a look.
